Well, Yeah! They did like each other! The episode called "Sisters", "Transformation" and "Date with Destiny" gives out the most clues! In "Sisters" he saves Starfire and Blackfire was jealous that Starfire had a boyfriend (Robin) so Black started to take Robin away from Star! In "Transformation", he's is the one that woried about Star the most and saved her from the Tamaranian Crysalis Eater!! And the finally one, "Date with Destiny", Star fights with Kitten for Robin! Then Fang says "Get your hands of my girl" to Robin and Starfire responds "Get your hands of my boy." And before that all happend, Starfire was dressed in a dress and beatifully! Then at the end Robin was dancing with Starfire! That episode was so funny! Oh yeah! Another episode that showed their love is called "How long is Forever?" When Star travels 20 years into the future she meets Cyborg, BB and Raven! But then she found Robin, 20 years older than his originall age! There was some hints of love in that episode! Don't you agree? XD
